6 Claims. (Cl. S25-19.5)

This invention relates to lm patches of the patch comprising a pair of members hingedly general character disclosed in Letters Patent of connected; the United States granted to me on the 30th day Fig. 7 is a perspective view of the same applied of August, 192i, No. 1,389,523, but embodying certo the overlapping sections of a film as in Fig. l.;

tain desirable and necessary improvements there- Fig. 8 is a section of the alternate form of patch 5 over, by means of which the adjacent ends of on line 8-3 of Fig. '7; `and. strips of film such as is used in production of Fig. 9 is an enlarged View of the same form of motion pictures and the like may be held together, patch showing the members thereof disposed at as when out or broken. an angle from their operative plane.

The marginal portions Fig. 3 is a longitudinal section of the same on of the bodies are formed with the apertures I3, 50 line 3 3 of Fig. 2; as in Fig. 1, and the attaching portions 9 and IE) Fig. 4 is a transverse section of the same on are formed on said members and have teeth l2 line l-l of Fig. 2; corresponding to the form shown in Fig. l.

Fig. 5 is a section on line 5 5 of Fig. 4; The second form described is applied to the Fig. 6 is a perspective view of another form of iilms before the attaching portions are bent at 55 too acute an angle after which said portions are bent inwardly and clinched over the edges of the lm section as in the case of the form shown in Fig. l. The joint between the members 3 and 4' may be formed so as to provide a type of joint which will not permit the flexing of the patch during use, as illustrated in Fig. 8, the end of the curl i4 of one member being limited by engagement with the socket in the curl I5 of the other member, or otherwise.

In both forms of device the advantages and desirability will be readily appreciated by those skilled in the motion picture art, for the reason that single piece patches frequently break, especially the teeth thereon and must be replaced, or they may be accidentally displaced from a lm in some instances to the disadvantage and inconvenience oi' an operator. The forms of patch shown herein are not susceptible to any such or other usual disadvantages and can be removed from the film only by bending the attaching portions outwardly so as to disengage the teeth I2 from the film sections and the patch body portions.

What I claim, is:

l. A film patch comprising: a plurality of members adjustably connected and having means on opposite portions thereof for engagement with the sprocket perforations of adjacent sections of a film for holding said sections together for use, said members having portions adapted to overlie the edges of said lin sections and to engage opposite surfaces thereof for clinching said sections.

2. A nlm patch comprising: a pair of members, means connecting said members for longitudinal adjustment one upon the other and transversely of the iilm, and means at the ends of said members for engagement with the sprocket perforations of adjacent sections of a lm for attaching said sections together.

3. A lm patch comprising: a pair of members adjustably connected and adapted to overlie adjacent sections of a film, said members having end portions adapted to be bent around the edges of and to underlie said film sections, and means on said end portions for engagement with the sprocket perforations of said lm for operatively connecting said film sections.

4. A film patch comprising: a pair of members adjustably connected at an intermediate point and adapted to overlie adjacent sections of a film, said members having end portions adapted to be bent around the edges of and to underlie said lm sections, and means on said end portions for engagement with the sprocket perforations of said lm for operatively connecting said film sections, said means including teeth formed on said end portions.

5. A film patch comprising: a pair of members adjustably connected at an intermediate point and adapted to overlie adjacent sections of a film, said members having end portions adapted to be bent around the edges of and to underlie said film sections, and means on said end portions for engagement with the sprocket perforations of said film for operatively connecting said film sections, said means including teeth formed on said end portions, and apertures in registration with and for receiving said teeth.

6. A film patch comprising: a member having a sectional body adapted to overlie and extend entirely across a section of film transversely thereof and an extension therefrom adapted to underlie said film, means on said extension for engagement with the sprocket perforations on said film for attaching said member in position for use, and means connecting said body sections for relative adjustment.
